The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Prostitution has for a long time been an understudied field in economics. Due in part to a lack of quantitative and empirical material, itself largely a result of the illegality or semi-illegality of the activity in most countries, the factors that explain the prevalence of, and pricing in, prostitution have remained largely undiscussed. In the last 20 year, this have begun to change: new theories ? notably by Edlund & Korn (2002), Rao et al (2003) and Della Giusta et al (2009) ? have been formulated and the rise of internet based escort sites have made large scale quantitative studies possible. This thesis examines if, and in what way, court documents can help expand the understanding of the economics of prostitution in Sweden.

On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.

This thesis discusses the Swedish drug policy and its principle of prohibition. In the world of today there is an ongoing discussion about prohibition and the concept of harm reduction. This thesis is an analysis of Swedish drug policy and an investigation as to whether the prohibition concept is in a state of Decline. It tries to answer the question; is the Swedish drug policy moving away from its prohibition principle towards a harm reduction principle? The recent debate, articles, documents and earlier research has been analyzed in order to find answers to my questions.

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a Decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in Decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.

To read and understand are essential competences for everyone in our society; at the same time reading comprehension among Swedish pupils is on the Decline. The Swedish school must therefore try to improve their instructions to increase the students' reading comprehension. The aim of the study was to describe how three reading comprehension strategies, if possible, could improve the reading comprehension for the students, including children with learning disabilities, when reading texts of natural science in a third-grade class. The three strategies that were introduced were: to activate prior knowledge, to structure information and to record contents. The questions of the study were: How are the three strategies introduced in the classroom? Can the children with learning disabilities see any benefits for their reading comprehension when working with the strategies? How do the children with learning disabilities experience working with the strategies? Can the teacher see any benefits when working with the strategies? Is it possible to see any differences among the students' results, before and after completed intervention? Method: The results have been collected through observations and qualitative interviews, which make this a qualitative study.

The aim of this Master?s thesis is to examine the profession of librarianship by studying tasks in Swedish public libraries. The method is a textual analysis of articles inspired by the critical discourse analysis of Norman Fairclough. The theory applied consists of the profession theory of Andrew Abbott and the gender theory of Yvonne Hirdman. The questions raised are: how do librarians speak about their tasks, which discourses can be constructed and how can profession theory and gender theory explain the result.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

På ostkusten mellan Södertälje och Vagnhärad ligger Tullgarn. Eken har sedan långt tillbaka varit en given del av landskapsbilden runt Tullgarn. Det har funnits en oro för att ekförekomsten på Tullgarn varit avtagande och att dess framtida förekomst skulle var osäker. Denna osäkerhet har varit en stor del till varför detta examensarbete initierats. Syftet med arbetet har varit att titta på hur ekförekomsten har förändrats mellan 1973 fram till 2014 och bedöma ekens aktuella förekomst och livskraftighet.

Through the birth and arise of the Internet people has been given great opportunities to make selective selfpresentations online, which in the long run has resulted in an easier retaining of the self- esteem than in the offline world. Simultaneously, the self- esteem has been viewed as a cause for both success and failure since it plays a vital role regarding our attitudes, emotional reactions and behavior. On this basis I wanted to study the relation between self- esteem and self-presentations closer. The purpose of the study is to describe and analyze how some users who publish training photos of themselves on Instagram experience how they present themselves within this forum and how these presentations affect/ are affected by their perceived self-esteem in their everyday life. The study is based on theories regarding self- esteem through Maslows? hierarchy of needs, the inner and outer self-esteem, and social comparisons.

This thesis aims to study brand change, which can be of interest since a brand during its lifetime can be expected to meet a lifecycle consisting of five phases; innovation, introduction, growth, maturity and recession. In order to avoid the recession phase and the sales Decline that follows there is a need for a change of the brand.In order to study brand change, theoretical framework is compared to two real world cases that have gone through an active change.The conceptions of positioning, repositioning and revitalization are clarified. Positioning deals with how brands are located in customer?s minds as well as on the real market. Repositioning implies a change of the current position and is also often a move towards a new market segment.
